Leaf-miner: Vertically oriented corridor in the leaf sheath (very rarely in the blade). Often several mines together, sometimes confluent. Frass in dispersed little granules. Pupation within the mine (Bladmineerders van Europa).

Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.

Mandible with two teeth (de Meijere, 1937a, Nowakowski, 1973a) (Bladmineerders van Europa).

Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).

Relatively slender; front spiraculum weakly bifid with about 10 bulbs; rear spiraculum fist-shaped with ca. 15, irregularly arranged large bulbs (Venturi, 1946a) (Bladmineerders van Europa).

Hosts in Great Britain and Ireland: Unknown.

Hosts elsewhere:

Arundo donax     Spencer, 1990: 365
Phragmites australis   British Wild Flowers by John Somerville et al. Spencer, 1990: 365

Time of year - larvae: Larvae in June-July and September-October (Nowakowski, 1973a) (Bladmineerders van Europa).

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Added to the British list by Gibbs, 2006.

Distribution elsewhere: Widespread in continental Europe including Belgium, Corsica, Czech Republic, French mainland, Hungary, Italian mainland, Poland, Spanish mainland, Yugoslavia (Fauna Europaea).
